Abstract

With the first data sample collected by the CLEO-c detector at the

ψ (3770)

resonance we have studied four exclusive semileptonic decays of the

D^{0}

meson. Our results include the first observation and absolute branching fraction measurement for

D^{0} \to ρ^{-} e^{+} ν_{e}

and improved measurements of the absolute branching fractions for

D^{0}

decays to

K^{-} e^{+} ν_{e}

,

π^{-} e^{+} ν_{e}

, and

K^{* -} e^{+} ν_{e}

.
